Protected cushioned wheel.



1' UN TED STATES HENRY J. NAGLE, oFn BoTTsTowN, PENNSYLVANIAJ.FPROITECITED ousmON I I PATENT OFFICE,

Patented May To all whom itmay concern: 7 Be it known that ,I, HENRY J.NAGLE, a citizen of the United States, residing at Abbottstown, in thecountyof Adams and State of Pennsylvania, have invented certain newand-useful Improvements in Protected Cushioned Wheels, of which-thefollowing is a specification.

more particularly to a wheel and shaftbox therefor.

The ob'ect of my invention is to provide a vehicle w eelhaving an outerprotective tire and an independent cushion tire, thus main- Fig. 2 is aninterior face view of t e axle box form of wheeled vehicle,

- applied to the rear or driving axle, of an-autoand hub of thecushioned wheel. Fig. 3 is a vertical section of the said box and hub.

While my invention ma be applied to any have shown it. as

mobile. 2 designates the said axle and 3 the driving gear anddifferential usually carried thereon.

4 indicates the vehicle body supported on the ordinary body-springs 5 5,which in turn bear on and are attached to the axle boxes.

These are preferably vertically elongated or' rectangular,.as shown inFig. 2,and form each. an inclosing casin having outer and inner sldeplates 6.

fall in said boxes. Fast on the axle and located within each box-is acollar 2 of a diameter wider than the slot 6" and of a width aboutequalto the width of the box 6, to revent the lateral movement of the axle, wile allowing the axle freedom of vertical movement.

- Projecting outward from the lower margin of box 6 is a smallhorizontal shaft 7 on which rotate an anti-friction bearing 8.Preferably bearing, and to that end I reduce the diameter of the shaft 7and place between it and the bearin 8 the balls 8, said balls being heldin p ace by the collar 7 which is slightly smaller than the interiordiameter of r I the My inventionrelates to vehicle wheels, and

the box '6 with a face plate 9.

make this anti-friction bearing a ball the bearing 8. This-bearing I toin the form of a thimble or cap inclosing the .endof the shaft'7-and theballs rotatingthe'rein'and projecting partly. over Ithe- 6o groovedcollar 7- with which it may havea rotatable engagement of anysuitablekind. I] have shown a screwpin 8'." its-engaged wi h ooved collar 7 Thisrevents. the

capom being removed from t e end of the shaft 7 without first removingthe screw pin.

It will be'understood from this description f that'lthe thimble 8forming the anti friction bearing, has a rotation around: the shaft.1 7

and is su orted on the balls 8. j

While .may attach the shaft 7 to thebox 6' in any desired manner, I haveshown it as havinga flat shank 7 projecting under the box 6 and boltedthereto, and to provide a,

wheel may bear, I provide the upper end of This may be fastened to thebox 6 many desiredmanner' and may extend down on either side of the slot6.

Tothe end that,I bearing surface for the said hub 11' of the"independent wheel, I form the rotating. thimble 8 with a flange 8* aainst the outer;

face of which said hub will ear, said outerface being inthe samevertical plane as the outer'face of plate 9. Uponth'e end of the axle isri idly attached the hublO of an outer wheel w ich is ada ted to turnwith 'said,

- surface against which the hub .11 of the 75,

may provide. al'ower axle 2, or, if the axe be afixed one, it is adatedto rotate independently on the axle. As have shown my invention asapplied to automobiles, I' have shown a driving-axle and therefore thesaid 'outer ;wheel .-,i s fast thereon and turns therewith.

10 indicates the ,felly of-a wheel provided with any suitable tire, and10' designates the spokes which connect the hub 10 of the Wheel v withthe said felly. The felly rojectsinwardly beyond the inner su ace of,the too s okes .10 andwithinsaid felly and inside of t e spokes of theouter wheel is the cushion'' tired wheel 11. The tire 1,1 of this .wheelmay be of any suitable resilient material, as rubber .or pneumatic tire.H and spokes 11'. It will be noted in the I drawings that the interiordiameter of thje' hub 11" is such that while the center of the wheel isco-incident with the axis of the axle 2, yet the inner face of the hub11" will bear .1 10- against the rotating 'thimble- 8. The "two w eels10 and 11 are independent of each other, as far as movement in avertical lane is concerned and as far as the resilience of the The innerwheel, how-.

movement by the spokes 10 of the outer 9 and the flange 8 of iub bearsagainst the the plate 9 and against the wheel and by the date thethimble 8. 'fnis l outer surface of face of the flange 8 as shownclearly in Fig.

on the tire ahd fellies of the wheel 10 may be use my invention may Asform of outer ny form of protective tire thereon. The inner wheel alsomay have any form of elastic tire and may be It is for this reason that-I have shown the simplest form of wheels in order 'that the principle ofbefore statedaniy d an a unnecessary details.

It will be seen that inthe operation of my invention anv shock or jarwill be received said shock or jar will be transmitted more or less tothe axle as is usually the case in vehicle constructions, but that thevertical movement of the axle due to such jar will not except throughthe cushioned wheel I 1. The jar will be very much deadened by thecushioned' tire of this wheel andwill then pass to the. projecting shaft7 and be transmitted sn htly' to. the box 6. The jar upon the box 6,owever, will be taken by the springs 5 which support the vehicle body.Any jar of the machinery, however, will not be transmitted to thevehicle body for the reason that the shaft 2 has vertical movement inthe box 6 and'is independent'of the said box and any vibration of tire11 and then to the axle box 6 as before movement of the wheels 10 and11., the wheels are kept from anylateral vibration or strain'byreason ofthe connection of the outer .wheel to the axle 2 and of the combinationof the two wheels being heldin position against the bearing plate 9. a

Vhile I have shown the simplest form.of my invention I wish itunderstood that I m y modify it in man ways and elaborate its detailswithout 1n te slightest departing from the principle. thereof.

claim is:

,1.- In a vehicle, a wheel provided with a cushioned tire,in.comb1nat1on with a wheel .having it protective tire extending overthe tread surface of the cushioned tire, said last named wheel beingmovable independent of wheel mounted on'the said axle not heobscured byany wheel 10, that.
